Reaction Steps

tert-Butyl N-(3-bromopropyl)carbamate (40.86 mg, 0.1716 mmol) was added to a stirred solution of 3-[2-[3-amino-6-(4-isopropylsulfonylphenyl)pyrazin-2-yl]ethynyl]phenol (45 mg, 0.1144 mmol) and K2CO3 (39.53 mg, 0.2860 mmol) in DMF (1 mL) and the reaction mixture warmed to 65° C. for 16 hours. The reaction mixture was partitioned between DCM and saturated aqueous NaHCO3 and stirred for 5 minutes. The layers were separated by filtration through a phase separation cartridge and the aqueous layer retained was washed with DCM (×2). The combined organics were concentrated in vacuo and used directly in the next step.
